It graphs your functions, gives exact answers and shows the steps behind derivatives and integrals. Everything runs on your device, so it works without internet or an account, and you buy it once instead of paying for a subscription. Graphs - 2D plots of functions, implicit equations, polar and parametric curves, run charts and vector fields. PocketCAS marks zeros, extrema and intersections. In full screen, tap a mark to read its coordinates. - 3D surfaces and space curves with soft light and shading. Drag to turn them, pinch to zoom, add a floor grid or pick another color map. - Animated plots: use the variable anim in any plot. Suggestions and steps - Under each function, suggestions show what to look at next: its derivative, zeros, extrema, integral or a plot. The answer is already in the suggestion. Tap it to add it to your document. - Functions get a small plot right beside the result. - Calculation steps show the rules behind a derivative, an integral, a differential equation or an extremum, one row per rule. Exact answers - Algebra: solve equations and systems, simplify, expand and factor expressions, divide polynomials. - Calculus: limits, derivatives, integrals, Taylor series and sums. - Linear algebra: matrices, determinants, inverses, eigenvalues and eigenvectors. - Differential equations: ordinary differential equations, solved exactly. - Units and constants: enter physical formulas with units and convert the results. - Scripts: define your own functions with conditions, loops and recursion. Reads like your textbook - Results look the way they do in a textbook: fractions, roots, sums, integrals and matrices. Long results wrap to the width of your screen. - A math keyboard with every function in reach. Your recent functions sit above it, and a hint shows what goes between the brackets. Made for daily work - Documents keep your calculations and plots together, so you can pick up where you left off. - iCloud syncs your documents between iPhone, iPad and Mac. The Mac app is a separate purchase. - Export: print or share plots, entries or whole documents as PDF. - Import: reuse functions from other documents, or load data from CSV files. - Help built in: the reference explains every function with examples, and tutorials get you started. A free version of PocketCAS lets you try the interface and many features first. What users say "This program has an incredible amount of power for such a compact program.

They use the same kernel known as Xcas. Though HP provides a completely free emulator for computers (25 bucks for iOS), it's frustrating to navigate through formulas in an 'exactly emulated' window with a 320*240 resolution. Besides, I'm happy to find this app supports more 3D graphing functionalities than HP Prime. Such as 3D parametric plots, lines, planes... and even animated plots! I've also tried the app from Xcas website, only finding it's not updated and maintained for newer macOS versions for a long time. And to be honest, the original Xcas app is really hard to use. An added bonus is that this app supports the Handoff function. It conveniently pops up on the dock of my Mac, and with just one click, I can seamlessly transition it onto my big screen. Don't hesitate to get it! Totally worth the 50 bucks for all your Apple devices! -- AutoPilot#ZUTF, 2024-01-01 ### ***** "Great CAS" This is a very good program. XCas/GIAC on the ipad! The GIAC kernel looked up-to-date (9/2023), so the dev appear to be keeping it current. The 900 or so page manual written by the GIAC developers(?) Is excellent. The only problems i have had involve file I/O but that is because of the protected nature of ios sandboxing, not this program. There are ways to read and write files from the menus. I highly recommend it. -- sbergman123, 2023-12-03 ### **--- "NO LONGER WORKS on iOS 12.5" After the latest update, this app no longer runs on iOS 12.5. If the Devs don't want to support this version of iOS anymore, that's fine, but please don't push an update to my phone that no longer works on it! -- Uncle_Brian, 2023-09-22 ### ***** "Love it - but variables can't be added" Great calculus app. Use it all the time as well as in classroom (DSP). Now retired from teaching but still use it. The latest version on iPadPro 2 doesn't allow adding or editing your variables. Can still declare them inline as usual, but the handy feature when dealing with a set of similar graphs is greatly missed. Still a great app. -- Toneman182, 2023-08-23 ### ****- "Wonderful for circuit analysis" I use this app for solving systems of equations when I design linear and non electronic systems -- By c# software developer, 2023-03-13 ### *---- "Waste of Money" Very basic calculator that needs developing. A lot of developing if they want to charge $20. Free apps have better buttons and solutions. Graphing is very off when it comes to trig functions. I just wasted $20 because I was going off the stars. -- Mattfranksucks, 2022-12-10 ### ***** "Absolutely amazing" Incredibly simple to use. love that you can save the calculations in documents. Brilliant! -- Zpexs, 2022-08-05 ### **--- "Not worth it but helpful with lower levels of math" I will read the “manual” but right off the bat; first equation entered calculate pre-algebra not calculus III… and quick reference to nth terms formulas not found or I didn’t see them. It’s very basic and just not what I was looking for. Search for a few calculus “term phases” and not there. It’s disappointing; but could help others? Not found (all) power series applications Geometric functions (w/ long division) and more. But honestly I doubt there is “what I am looking for” out there…this one is just not for me. -- stay young have fun, 2022-04-23 ### ***** "Pocket CAS is a good program" I have been using Pocket CAS for a lot of years. I use to assist me in my personal studies. The program is extremely useful in being able to take notes on the same sheet as the calculations. My criticism is, that the operators manual needs to be more in depth. Also the order of operations needs to be clearly explained, as it is difficult to recognize how the order in which the calculator is performing the math. It would also help if the calculator kept all terms in the same order as they were written. This is a good program, but it would be better if you could make changes that i mentioned above. Thank you for listening. -- 001lb, 2021-09-20 ### *---- "Unaddressed Errors" When I first purchased this app, it was to help with collegiate math classes. I noticed an interesting quirk which I see has remained unaddressed: The stddev function doesn’t not return the standard deviation. It returns the population standard deviation. I verified this using several other computer algebra system apps, a stats calculator, consulting my stats professor, and consulting a college math tutor. I contacted the maker of this app quite some time ago about it and all I got was push back. Even after providing evidence that the function’s return is incorrect based on the function’s name. The stdDev function returns the correct result, despite being listed as an alias for stdDev. It is not. Confusingly, it returns the same result as stddevp which is supposed to return the population standard deviation. It does not. It returns the standard deviation, as stdDev does, even though stdDev’s in-app description explicitly states it is returning the population standard deviation. Go check for yourself. -- nihilon, 2021-08-24 [View all Mathematics with PocketCAS Pro reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Mathematics with PocketCAS Pro Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | Ecuador | Education | #78 | | Top Paid | Nigeria | Education | #79 | | Top Paid | Lebanon | Education | #91 | | Top Paid | Pakistan | Education | #93 | | Top Paid | Austria | Education | #102 | | Top Paid | Greece | Education | #109 | | Top Paid | Portugal | Education | #113 | | Top Paid | Australia | Education | #131 | | Top Paid | Finland | Education | #139 | | Top Paid | United States | Education | #146 | | Top Paid | Hungary | Education | #162 | | Top Paid | France | Education | #165 | | Top Paid | Denmark | Education | #166 | | Top Paid | Argentina | Education | #167 | | Top Paid | Colombia | Education | #171 | | Top Paid | Mexico | Education | #174 | | Top Paid | Belgium | Education | #178 | | Top Paid | Switzerland | Education | #181 | | Top Paid | Brazil | Education | #188 | | Top Paid | Chile | Education | #211 | | Top Paid | Spain | Education | #223 | | Top Paid | Peru | Education | #227 | | Top Paid | Netherlands | Education | #247 | | Top Paid | Israel | Education | #248 | ## Mathematics with PocketCAS Pro Discovered Keywords -
